Final answer:
To make 10 g of 1,4-dihydropyridine A, the amount of reagents necessary is 11.24 g.
Step-by-step explanation:
To calculate the amounts of all reagents necessary to make 10 g of 1,4-dihydropyridine A, we first need to determine the theoretical yield of compound A. Assuming a 89% yield for the synthesis of compound A, we can calculate the theoretical yield as follows:
Theoretical Yield of Compound A = 10 g / 0.89 = 11.24 g
Therefore, the correct answer is option (a) 11.24 g.
